Ubuntu 20.04 with Wifi on iMac 2019 (MacOS 11 - Big Sur)

The purpose of this document is to summarize some of the things I had to figure out to successfully install Ubuntu on my iMac '19 27" 5K, a.k.a. iMac 19,1.

t2linux

From what I could find, iMac's do not have the t2 security chip. However, it does share hardware (and firmware) with contemporary Macbook Pros. For this reason, the t2linux.org website contains lots of helpful information about how to install Ubuntu on an iMac.

However, the guides on the t2linux website did not work for me when I ran it, so I had to mix and match some old pages from the wiki to make things work. Also, most issues are focused on Macbooks, not iMacs.

Emacs 29 + Doom setup for MacOS

Installation (from Doom guide)

https://github.com/doomemacs/doomemacs/blob/master/docs/getting_started.org#with-homebrew

I use emacs-plus because of the emacs-mac issues with emacsclient. See this issue: railwaycat/homebrew-emacsmacport#52

EN + SE on the Moonlander

I've been switching back and forth between English and Swedish for programming / chatting since.. forever.

Having bought the ZSA Moonlander, one of the goals was to eliminate switching.

There are two possible routes:

1. Use a Swedish layout and put EN keys in better positions
2. Use an English layout and somehow manage to insert åäö

Using decorators in React Native

1. Install babel plugins to enable decorators.

   npm install babel-plugin-transform-decorators-legacy --save-dev

2. Create or update your .babelrc file in root folder:
